Specification of Letters Patent.

Patented Oct. 6, 1914.

Application filed July 19. 1912. Serial No. 710,453.

To all Whom it may concern Be it known that I, CAsnnn on PRoszYN- sin,subject of the Emperor of Russia, residing at London, England, haveinvented certain new and useful Improvements in Kine matograph (amerasand Projecting Apparatus. of which the following'is a specification.

This invention relates to kinematographic cameras and projectionapparatus in which a broad film is used, the film being movedintermittently both laterally and longitudinall y in order that thepictures photographed are arranged in parallel rows transversely of thefilm.

The object of the present invention is to provide an improved camera andprojection apparatus of the above kind which Will work efficiently, andwill permit of regulation of the film feeding mechanism, so as to insureaccurate registration of the pictures with the lens apertureirrespective of changes in the width of the film due to shrinkage.

In the accompanying drawings: Figure 1, is a sectional elevation of oneform of kinematograph apparatus according to the invention, the sectionbeing taken on II Fig. 2. Fig. 2, is a sectional plan. Fig. 3, is adetail sectional viewillustrating the gate and film rolls. Fig. 4, beinga similar view of a modification thereof. Fig. 5, is a part rear viewcorresponding to Fig. 4. Fig. 6, illustrates a piece of film. Fig. 7. isa detail view of regulating mechanism for the film. Figs. 8 and 9 are asectional view and a side view of a modified form of adjustment for theend of the pawl rod.

In carrying out the invention, according to one form, a broad fihn (1,having two series of perforations b, and c, the perforations of oneseries being elongated as is known in the art to allow of shrinkage ofthe film, is passed in the form of a roll (I, onto a. stationary spindle6, Figs. 1 and 3. so that it is free to slide thereon, and can also befreely unwound therefrom. The film (z, is passed from the roll (Z, downbetween two parts 2 and 3, of what is usually called the gate. Thiscomprises a stationary part 2, having an exposure opening 5, therein,and a hinged part or gate proper 3. also having an exposure opening 5,and fitted with a spring pad 4, which gently presses the film againstthe stationary part 2, when the hinged gate 3, is moved into the properfrom right to left closed position with its end 3, in engagement withthe spring catch 14, Fig. 2. The hinged gate 3, has a bent wire guard 8,over which the film a, is passed on its way to a spool e, mounted on arotary spindle 7, the end of the film being clipped on to the spool e,by a clip 7 The spool c, is free to slide on the spindle 7, but iscaused to rotate therewith, for the purpose of allowing the film a, tomove laterally, as well as longitudinally as hereinafter explained. Topermit of this relation between the spool and its spindle 7, the spoolis provided with a key-way 7, and the spindle 7, is provided with a key7*, the key being a loose fit in the key-way 7". The perforations b, andc, in the film a, are engaged by the teeth of sprocket pinions 1, whichare mounted on a tubular shaft 9. The tubular shaft 9, is provided witha slot 12, Fig. 1, in which the rack 11, slides, the rack 11, beingconnected to the piuions 1, Fig. 2, so that the pinions 1. can slidelongitudinally along the tubular shaft 9. but are obliged to rotatetogether with said shaft.

The rack 11, is provided with two sets of ratchet teeth of oppositehand, the teeth of one hand alternating with the teeth of the otherhand, as clearly shown in Fig. 2. A pawl rod 37, situated within thetubular shaft 9, is provided with two pawls 41', 43, also of oppositehand. The pawls are set apart as shown in Fig. 2, and are angularlydisplaced as shown in Fig. 3, so that only one pawl can be in operativeposition at a time to engage with the rack 11. \Vhen the film is to befed from left to right the rod 37, is first rotated so as to bring thepawl 13, into operative position to engage with the corresponding set ofteeth in the rack 11, the other pawl -11, being thereby moved into aninoperative position; whereas when a feed is required, the pawl rod 37,is first rotated to bring the pawl 41, into operative position and thepawl 43, into an inoperative position. The pawl rod 37, which is free atthe end 40, passes through two bearings, 38, 29 in the left hand end ofthe tubular shaft 9. It is left free at the end 40, so that it canspring away from the rack 11, when either of the pawls 41. 43, isengaging with the rack 11. but is on its return stroke and thereforeslipping over the tooth with which it is in contact. The opposite end ofthe rod 3', isfitted with two adjustable coltated, as just lars 64, 64,screwed thereon and adapted to be engaged with the forked end 63, of alever 62, Figs. 1 and 2.

The lever 62, is pivoted at 66, to a lever '67, which in turn is pivotedat 68, to a stationary bracket 69. The lever 62, is forked and therebyprovided with two abutment surfaces 62, and 62 Fig. 1, which are adaptedto be engaged by either OfrtWO cams 53 and 54, according to which cam isbrought into operative position opposite to the lever. One cam 53, isbrought into the operative position when the film is to be moved fromleft to right and the other when it is to be moved from right to left,the cains being set .at 180 apart. The third cam 52, is intended todepress a lever 57, pivoted on a rod 58', Figs. 1 and 2, the lever 57,being provided with a spring pawl 59, adapted to engage a toothed Wheel60, mounted on the tubular shaft 9, for the purpose of imparting to thesaid shaft the requisite rotary movement for shifting or feeding thefilm longitudinally through the medium of the pinions 1. The lever 57,is returned to its normal position after each depression, by means of aspring 57 Fig. 1. The three cams 52, 53, 54, are mounted on or formed inone piece with a sleeve 61, Fig. 2, which is free to slide on a shaft55, but is caused to rotate therewith, for instance, by a pin 61, whichpasses throughthe shaft 55, and enters a slot 56, in the sleeve 61. Thesleeve 61, is provided with a collar 51, which is engaged by-a lever 46,which is pivoted at 48, and has a pin 49, on it which enters the camslot 49, in a wheel 34, on the rotation of which the lever 46, isoscillated periodically and reciprocates the sleeve 61, so as to bringthe cams 53, 54 alternately into and out of engagement with the lever62. The reciprocation of the sleeve 61, also brings the cam 52, into andout of engagement with the lever 57. The lever 46, has another arm 46,which is forked at its end 47, and the forked end 47, engages with acollar 43, capable of sliding on the tubular shaft 9. The collar 43, hasa pin 44, Fig. 2, which engages in a helical slot 44", in the shaft 9,so that it is caused to rotate in relation to said shaft when it slidesthereon, under the action of the lever 46. The pawl rod 37, has a crankpart 42, which passes through a wide slot 45, in the tubular shaft 9,Fig. 2, and fits in a slot in the bore of the collar 43, so that whenthe said collar is rodescribed, it rotates the pawl rod 37 sufiicientlyto move=one of the teeth .41, or 43, into engagement with the rack 11,andhthe other tooth out of engagement therewit The wheel/34, is mountedon a shaft 49, adapted to be rotated by a handle 36. A gear wheel 33,on. the shaft 49', meshes with a pinion 32, on the shaft 55, and therebyrotates said shaft which carries the cams 52,

53, '54, before referred to. The wheel 33, also meshes with a pinion 31,on a shaft 31, on which is mounted a wheel 23, which meshes with a wheel22, that drives a pinion 21, on the spindle 21, of the shutter 20. Theshutter 20, is clamped on the spindle 21, by means of a nut 29, and isalso prevented from moving relatively to said spindle by means of a pin30, carried by a boss 30', the pinpassing through a suitable perforationin the shutter 20. The shutter 20, rotates within a metal cap 28 mountedwithin the main casing 27 so that it isentirely protected. A- tube 15,projects through the cap, and an opening 27 is provided in the casing27, opposite to said tube 15, which is fitted with a pinion; 16,operable by a rod 17, fitted with a slotted head 18, so that it can beeasily rotated'by a coin or screw driver in order to focus the lenswhich is carried in a tube 13, telescoping in the tube 15, and having arack 19, adapted to be engaged by the pinion 16. The tube 15, is mountedupon the stationary portion 2, of the gate as shown in 3. If desired,the shaft 31, may be fitted with a handle 35, in place of the handle36'. The wheel 34, is provided with a tooth 34, Fig. 1, ,which drives atoothed wheel 7, on a spindle 7, of the spool e, .so that the spool isintermittently rotated at the same time that the pinions 1, are rotated.

The mechanism so far described is sufli- ,cient for the takingofphotographs, that is to.say, I have so far described the camera, and itsgeneral operation may be summarized as follows :-Assuming the parts ofthe mechanism to be in the position shown in the drawings, except thatthe movable gate proper 3, is in its closed position shown in Fig. 3,and not in its open position shownin Fig. 2, the pawl 41, has justfinished a series of reciprocations which through the medium of the rack11-, have moved the pinions 1, from an extreme position at the right toan extreme position to the left. The mechanism is shown just on thepoint of change. Rotation of the handle 36, will cause the shaft 49, torotate and therefore, the rotationof the wheel 34 thereon. The curved,part 49 of the cam slot 49, in the wheel 34, is justabout to receive thepin 49, and therefore, the lever 46, is justabout to. move the sleeve61, on its shaft YV-hen'thisv occurs the cam 52, will be brought overthe lever 57, and the cam 53, which in Fig. 1, is shown in engagementwith the lever 62, will be moved awaytherefrom and the cam 54, will bemoved into engagement therewith. At the same time that this change ofthepositions of the cams will take place the arm 46', of the lever 46,will slide the collar 43 along the tubularshaft 9, and the collar 43,owing to the pin 44, and |slot 44, will receive a slight rotary motion,

which will partly rotate the pawl rod 37, relatively to thetulmlar shaft9, through the medium of the crank portion 42. This partial rotation ofthe pawl'rod 37. will bring the pawl 43. into engagement with the rack11. and the pawl 41, out of engagement therewith. The parts will thus bein position ready to begin a step-b vstep movement of the pinions l. andtherefore of the film from the left to the right. but before this occursa longitut'linal feeding movement of the film is necessary by the amountequal to the depth of another picture. It will be understoml that whilethe shaft 19 is rotating, the shaft 55, is also being rotated by the.medium of the wheels 33, 32, so that the cam 54, will he brought into asuitable position to pass between the abutments 61, 62 of the. lever(32. when the sleeve 61, is being slid along the shaft The continuedrotation of the shaft 55, will cause the cam 52. to depress the lever57, and through the mediuni of the spring pawl 59, and ratchet wheel 60.to rotate the tubular shaft 9, and therefore. the pinions ll, thereon,thereby effecting the necessary longitudinal feeding movement of thefilm. When this has been completed the cam :74, will continue tooscillate the lever 62. and the latter by means ofits forked end 63, andthe collar 64, will reciprocate the pawl rod 37. This reciprocation willcontinue until the pawl 43, has engaged sutlieient teeth in the rack 11,to have moved the film step by step from extreme position on the left toits extreme position on the right. By the time that this has beeneffected the cam wheel 34, will have made a half revolution so that acurved part in the cam slot 19', similar to the curved part 49 but onthe opposite side of the wheel 34, will have reached the pin 49, readyto move the lever 46, in an opposite direction to slide the sleeve 61,so as to move the cam 53, into operative position,

with regard to the lever 62, and'the cam 54,

out of its operative position. It will at the same time. bring the cam52, again over the lever 57. and also slide the collar 43 through themedium of the arm 46, so that the pawl 43', will be brought out ofengagement with the rack 11, and the pawl 41, into engagement. andmoreover, so that the continued rotation of the shaft 5:"), will,through the medium of the cam 52, and lever 57, the pawl 59, and ratchetwheel 60, again rotate the tubular shaft 9, and pinions 1, to impart afurther longitudinal movement to the film. It willv be understood thatthe cam 52. is never over the lever 57, while either of the cams 53, or534, is opposite to the lever 62. but that it is over the lever 57, andeffects the depression thereof during the change of positions.

Briefly stated the operation of the mechanism consists in: (a). Thereciprocation of of registration. between the pawl rod 37. to effect astep by step movement of the pinions 1, carrying the film, first fromleft to right and then from right to left. (6). The intermittentrotation of the tubular shaft and pinions 1, during the change of thestep by step motion of the film in one direction, to that in the other.so as to effect the necessary longitudinal feed of the film to expose afresh lateral strip of film for another row of pictures. (0). Theintermittent rotary movement of the pawl rod 37, relatively to thetubular shaft 9, before each change in the step by step movement, inorder to bring one pawl into engagement and the other pawl out ofengagement with the rack connected to the two pinions. As any slightinaccuracy ,or lost motion between the pawls 11, and 13, and the teethof the rack 11, might lead to want the first picture of a row and thelast of the preceding row on the film, the pawl rod 37, is provided withadjustable collars 64. as shown in Figs. 1 and 2. If the right handcollar (i-t, be adjusted once and for all, it may be regarded n as fixedrelatively to the pawl rod 37. Thus, the extreme position of the pawlrod 37. to he right at the end of each stroke will be determined. Anyadjustment of the left hand collar 64, will increase or decrease thelost motion between the end 63, of the lever 62, and the said collar sothat by adjusting it, the extreme position of the pawl rod 37, in itsstrokes to the left can be varied. A more convenient arrangement,operable from outside the camera casing is shown in Figs. 8 and 9, andcomprises one collar 64, fixed on the shaft 57, once and for all in itsproper position. A slotted sleeve 641, roceives the end 63, of the lever62, which end need not be forked as in the previous example described.Thesleeve 641, also receives an adjusting screw 371. The screw 371passes through a bush 271 in the wall of the casing 27, and can thus beoperated from outside. If the screw 371, be rotated so that it isscrewed outwardly the lost motion or clearance between it and the end63, of the lever 62, will be increased. If it be screwed inwardly thelost motion or clearance will be decreased. The length of stroke of, andthe extreme position of the. pawl rod 37, to the left can thus be variedas required.

The mechanism so far described. will suffice, so far as the use of theapparatus as a camera is concerned, but as it is desirable that the sameapparatus shall be usable as a projecting apparatus some adjustment muste provided to allow for shrinkage of the film during development. \Vhena negative film is developed a positive film is obtained from it anddeveloped and this positive is used for projection purposes. \Vhen itshrinks all the pictures shrink in proporlt i tion, consequently unlesssome adjustment is provided the pictures will not register with theexposure opening, and the registration will get worse as the row ofpictures progresses step by step or picture by picture across the saidopening. Moreover as the teeth of the rack 11, are of a determinedpitch, a mere variation in the stroke of the pawl rod will not suffice,for if the stroke of the pawl be merely shortened that is, made lessthan the pitch of the rack teeth, it will fail to engage with the nexttooth on each return stroke. On the other handiif the stroke he merelyincreased so that it exceeds the pitch of the rack teeth it will movebeyond the next tooth on each return stroke and there will be a periodof idle motion so that the actual or effective movement of the rack willremain equal to the pitch. To meetthis difficulty I provide means, whichwill retard or accelerate the movement of the pawl while it is actuallyin engagement with the rack teeth, the amount of retarda tion oracceleration being such that the effective stroke of the pawl is alteredby an amount equal to the displacement of the first picture due to theaforesaid shrinkage. The movement of the pawl is retarded during thestep by step movement of the film in one direction and acceleratedduring the movement in the opposite direction.

The means for retarding and accelerating the movement of the pawl ismade adjustable so that the degree of retardation and acceleration maybe varied to suit the particular film'being passed through theapparatus. These means comprise a pivot 66 for the lever (32, Fig. 1,which is not stationary but one which moves gradually and uniformly tothe left or to the right accordingly as the pinions 1. and film thereonare being moved step by step to the right or left. To effect thisoscillation of the pivot 66, it is carried by a lever (57, pivoted on apin 68, carried by stationary brackets 69, Figs. 1 and 5.

A pair of levers 70. preferably formed in one piece. are mounted on pins71. in stationary brackets 71. The lever 67, has a slot 73. and thelower arms of the levers 70 are also slotted. A rod 74, passes throughthese slots, the wire being bent and extended upwardly to a bracket 77,where it is fitted with a nut 65, which will allow the rod 74, to swingslightly and which can also be rotated to raise or lower the rod 74, inthe slot 7.; A spring 75, constantly pulls the lever (37, and thcrcfore,the levers 70, toward a cam 72, mounted in the shaft 4}). The cam 72,has a uniform rise and fall. It makes half a revolution while thepinions 1, and therefore, the film makes a complete step by stepmovement or travel from left to right and another half while they make acomplete travel from right to left. If the rod 74, is drawn right up tothe top of the slot 73, the effect of the cam 72, on the lever 67, andtherefore, the amplitude of oscillation of the pivot 66, will benegligible, and this is the *ase when the apparatus is used as a camera.But as the wire 74, is lowered so will the effect of the cam on thelever 67, and therefore the amplitude of the oscillation of the pivot06, be increased. The lever 67, will oscillate and the pivot 60. willmake one movement to the right or left for each complete lateral step bystep travel of the pinions 1, and film thereon. The result will be thatthe effective movement or step of the pawl rod 37, will increase whilethe pinions 1, are being moved step by step in one direction and willdecrease while they are being moved in the opposite direction. As thecam 72, has a uniform rise and fall the increase and decrease will beuniform.

Should the pictures of a film be found to be out of register with thelens aperture, then the nut 05, can be rotated until the requiredadjustment has been effected. In a modification, the film. asillustrated in Figs. 4 and the film a, is pressed against the pinions 1.by means of grooved rollers 105, freely mounted on a rod 10ti so thatthey can slide thereon and follow the pinions 1, as the said pinions aretravelled step by step in one direction or the other. The rod 106, iscarried by end levers 101. each pivoted to a pin 102. and acted upon bya spring 103, so that the rollers 105, are pressed lightly against thepinions 1. A guide roller 104, is also carried by the levers 101, thefilm passing from the pinions 1, thence over the roller 104, to thespool a.

In a modification the sprocket pinions may be above the gate instead ofbelow it.

It will be understood that in the example illustrated the wholemechanism is mounted in one framework inclosed in the camera casing. Ifdesired, the film cam be contained in a box 80, and after passingthrough the gate can pass into another box 81, as

shown in Fig.4 these boxes being removablefrom the main casing to allowfor daylight loading and unloading. It will be obvious that the rod 37could connect the pinions 1, and the rack could then be reciprocated.
